Question

You wish to test the following claim (Ha) at a significance level of α=0.02.

      Ho:p1−p2=0
      Ha:p1−p2≠0

You obtain 163 successes in a sample of size 279 from the first population. You obtain 112 successes in a sample of size 235 from the second population.

What is the critical value for this test? (Report answer accurate to three decimal places.)
critical value, zc = ±

Please help me, How formula I can used in my calculator TI-84 to get critical value with two samples of sizes and two populations.
